Suspended Fifa president Sepp Blatter has suffered a "health incident" and is undergoing medical checks, Reuters report. A Fifa spokesman has confirmed the 79-year-old is undergoing "stress-related health checks" but is not in hospital.

"He is under medical evaluation − the doctors took him out for a few days, the doctors expect to him be back around Thursday or Friday (12 or 13 November) of next week," Blatter spokesman Klaus Stoehlker told Reuters.

"He is under tremendous pressure from so many sides and perhaps this is a little bit difficult for a man who is not the youngest."

Blatter, along with Uefa president Michel Platini, have been banned from all footballing activity for 90 days after Swiss authorities opened a criminal investigation into the world football's governing body.
